Which of the following is an example of an engineering control used to reduce pesticide exposure in a mixing/loading operation?
Answer: Using a closed-loop transfer system
A closed-loop transfer system is an engineering control that physically prevents contact with the pesticide concentrate during mixing and loading.
An ACE applicator notices a strong solvent odor and dizziness while applying pesticide in an enclosed warehouse. The FIRST action should be to:
Answer: Exit the area immediately and get fresh air
Dizziness and strong chemical odors indicate potentially dangerous vapor concentrations; immediate evacuation to fresh air is the priority action.
Which federal agency is responsible for registering pesticides and enforcing FIFRA requirements?
Answer: EPA
The U.S. Environmental Protection Agency (EPA) registers pesticides and enforces the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA).
A pesticide label lists the personal protective equipment requirement as 'chemical-resistant gloves.' Which glove material is generally LEAST suitable for most pesticide applications?
Answer: Natural latex rubber
Natural latex rubber offers poor resistance to many organic solvents and pesticide formulations and is also an allergen; nitrile, neoprene, and butyl are preferred for pesticide work.
What is the purpose of a 'buffer zone' specified on a pesticide label?
Answer: To establish a distance restriction protecting sensitive sites from drift or runoff
Buffer zones are label-required distances between the application site and sensitive areas (water bodies, schools, etc.) to minimize drift and runoff impacts.
When calibrating a backpack sprayer, the applicator discovers the output is significantly higher than labeled. The correct response is to:
Answer: Adjust the nozzle or pressure to achieve the labeled output rate before use
Applying at a rate above label specifications is an illegal pesticide use under FIFRA; equipment must be calibrated to deliver the labeled rate before application begins.
Which practice BEST reduces the risk of pesticide resistance developing in a target pest population during structural pest management?
Answer: Rotating between pesticide classes with different modes of action
Rotating between chemistries with different modes of action (e.g., pyrethroids, organophosphates, neonicotinoids) prevents selecting for resistance in pest populations.
